and the KT150 itself. To replace a fuse, using a screwdriver, simply turn the top of the fuse cap counter-clockwise. It
will spring out holding the fuse. Replace the fuse, push the fuse cap down and turn it clockwise; it will lock itself. If
you have any questions about doing this, please contact Your Allnic dealer for assistance.
If the AC mains fuse, located at the IEC input, has failed, it can be replaced with the spare fuse (5A, 250V, 20mm
slow-blow) provided in the tray in the IEC mount. Again, if you have any questions about doing this, please contact
Your Allnic dealer for assistance.
Of course, you will have to adjust the bias back into the area between the two parallel lines of the meter for a tube
when it is replaced. When replacing a KT150, first turn the bias screw counter-clockwise slightly to reduce current,
in case the bias is set too high for the new tube (since the old tube may have required additional bias). Bring the
bias up gradually to the middle between the two lines on the meter.
All consequences of changing or attempting to change tubes are borne by the user unless by express agreement
between the owner and an authorized Allnic representative. Allnic Audio and its authorized representatives are not
liable in any way whatsoever for any injury or loss incurred by the user or for damage to the A-2000 25
th
Anniversary SE, any of its parts, or tubes or replacement tubes resulting from the user changing or attempting to
change tubes.
